Humphrey, Guy R. published the artcileA novel synthesis of 3-bromo-1,2,4-oxadiazoles, Recommanded Product: 3-Bromo-5-phenyl-1,2,4-oxadiazole, the main research area is dipolar cycloaddition bromocyanogen oxide nitrile; bromoxadiazole.
The synthesis of 3-bromo-1,2,4-oxadiazoles I (R = Me2CH, cyclopropyl, EtO2C, PhCH2, Ph, 4-O2NC6H4, ClCH2, BrCH2) by 1,3-dipolar cycloaddition between BrCNO and RCN (same R) is described. Thus, Br2C:NOH in PhCN was treated with NaHCO3 to give 40% I (R = Ph) along with a small amount of the dimer II.
Journal of Heterocyclic Chemistry published new progress about 1,3-Dipolar cycloaddition reaction. 23432-94-2 belongs to class bromides-buliding-blocks, name is 3-Bromo-5-phenyl-1,2,4-oxadiazole, and the molecular formula is C8H5BrN2O, Recommanded Product: 3-Bromo-5-phenyl-1,2,4-oxadiazole.
